Plant Organ System Flashcards
What three things form a plant organ system that transports substances around the plant?
Roots
Stem
Leaves
What do xylem Tissues do?
Transport water and mineral ions from the roots to the stems and leaves to the red of the plant
What are xylem Tissues made of?
Hollow tubes strengthened by lignin
What are xylem Tissues adapted for?
Transport of water in the transpiration system
What are around the edge of stems?
Vascular bundles
What does the leaf cell make during photosynthesis?
Sucrose
What two things are root hair cells adapted for?
Efficient uptake of water by osmosis
Efficient uptake of mineral ions by active transport
What is active transport the movement of?
Minerals and vitamins AGAINST the concentration gradient from an area of low to high concentration
What does active transport occur in?
Living things
Does active transport need energy?
Yes
What is osmosis the movement of?
Water through a partially-permeable membrane from an area of high to low concentration of WATER
What is diffusion the movement of?
Molecules from a high to low concentration, down the concentration gradient until they are evenly spread
